From the outside, louvres are often the only visible portion of a complex ventilation system.
Being so visible, the appearance of any louvres is important. HVC weather louvres are available in 4 standard, high performance blade formats, and are available powder coated in any RAL or BS colour.

WL50 format weather louvres are best used for medium size applications. The larger blade profile is inherently stronger and more rigid than lightweight WL38 series louvres.
All louvres available from HVC are suitable supply applications, as well as return. The 50% free area also ensures high performance, and a good resistance to the ingress of rain is assured by the sloping blade design.
WL50 extruded aluminium weather louvres bring brilliant performance and a design perfectly suited to medium sized louvres together, and create a unit suitable for a huge range of external air terminal requirements,
Often timescale is a deciding factor in which manufacturer you choose. Manufacturing on a job by job basis gives us a turnaround time which often far and away beats our competitors, whether it be a regular square louvre, or an entirely custom made triangular unit in days rather than weeks, you are assured of excellent service.
We know that often a standard weather louvre will not do. Options can greatly enhance the functionality, insect and bird mesh prevent unwanted objects passing through the louvre, and integrated volume control dampers allow the adjustment of airflow right at the source. See the Options section to find out what we can do.
